Reconfigurable optoelectronic functionality implemented in a Ta2NiSe5/WS2 heterostructure toward multifunctional applications

Jones, and rapid rise/fall times of 46.9/48.9 μs, enabling effective photodetection. Furthermore, in the photoconductive mode, the device achieves basic synaptic functions for neuromorphic visual sensing, including short-term plasticity (STP), long-term plasticity (LTP), and the ability to "learn-forget-relearn" through photocarrier trapping/de-trapping processes, with a paired pulse facilitation (PPF) of 31.34%. This research introduces a novel strategy for the development of future multifunctional, integrated, intelligent, and compact optoelectronic devices.
